Summary: There is a need to develop novel clean systems for environmental and energy solutions. A novel tri-generation system for power, cooling and freshwater was developed using emergy analysis for evaluating economic and environmental aspects. The system performance was studied based on gasification temperature, combustion temperature and natural gas contribution. Various indicators were considered, including environmental loading ratio, Emergy sustainability index, Emergy investment ratio, Renewability scale, Emergy yield ratio, and energy efficiency. The system performance was optimized using response surface methodology. The results showed that increasing natural gas contribution improved system energy efficiency. The optimum conditions were found to be natural gas contribution of 1, gasification temperature of 1000 degrees C, and combustion temperature of 1403 degrees C, with prediction accuracy of response surface methodology below 5%.

Summary: This study aims to improve the combined power plant in Qom province by utilizing solar energy and a multi-effect desalination system. Various analyses, including energy, exergy, exergoeconomic, exergoenvironmental, emergoeconomic, and emergoenvironmental analyses, were conducted. The proposed cycle was optimized using a multi-objective genetic algorithm. The results showed that the addition of a solar-based thermal system increased the exergetic efficiency of the base plant by 1.91% and the new-designed plant could generate 33 kg/s of freshwater by integrating solar and desalination systems. The optimization results also indicated an increase of 3.22% in the exergetic efficiency of the proposed plant and reduced power generation costs, environmental impacts, freshwater generation costs, environmental impacts, and the emergy of the system.

Summary: This paper introduces a superstructure-based simultaneous optimum design and operation of seawater reverse osmosis (RO) system with boron removal under time-variant constraints. Three operational strategies are utilized to improve operability of the system under boron restrictions, including changing the activated number of pressure vessels, permeates split ratio, and pH values. Moreover, exergo-environmental and exergoeconoenvironmental analysis models are integrated, allowing for optimization of economic efficiency, energy utilization, and environmental impact in both design and operation phases.

Summary: Understanding how plants respond to environmental conditions is crucial for plant growth. This paper proposes using an Artificial Neural Network (ANN) model to predict plant response to environmental conditions in a Chinese Solar Greenhouse to improve crop production systems. Comprehensive data collection has been conducted in a greenhouse environment to validate the proposed prediction model. The results show that the Bayesian Neural Networks (BNN) models accurately predict crop performance.

Summary: The search for environmentally friendly renewable energy sources is driven by global climate changes and fossil fuel reserve depletion. Biomass, including sorghum, is a promising alternative to fossil fuels in Europe. Field experiments in Southern Ukraine showed that sweet sorghum can achieve a yield of 40.6 t/ha with an energy efficiency ratio of 11.18 under certain precipitation conditions, while grain sorghum's yield and energy efficiency ratio varied.

Summary: In this study, machine learning was used to predict the specific methane yields (SMY) using 14 features from lignocellulosic biomass (LB) characteristics and operating conditions in completely mixed reactors. The random forest (RF) model performed the best with a coefficient of determination (R2) of 0.85 and root mean square error (RMSE) of 0.06. Biomass compositions, particularly cellulose, had a significant influence on SMYs from LB. The RF model was also used to assess the impact of LB to manure ratio and determine the optimum ratio of 1:1 under typical organic loading rates (OLR). Experimental results confirmed the influential factors identified by the RF model and achieved a highest SMY of 79.2% of the predicted value. This work demonstrates the successful application of machine learning for anaerobic digestion modeling and optimization specifically for LB.

Summary: This study proposes a design space for creating accessible bimanual interactions in VR using unimanual input. They explore two dimensions, bimanual interactions and computer assistance, and develop new unimanual input techniques that map to bimanual interactions in VR. User feedback from a video elicitation study shows the need for additional settings and methods to make VR accessible to people with limited mobility.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
